“…The capacity of phycobiliproteins to function like free radical scavengers has been shown to center on their tetrapyrrols systems, contributing to their use in the cosmetics, pharmaceutical, and food industries 18,19 . Numerous accounts of analytical grade PBPs (purity ratio > 4.0) have shown that PBPs possess exceptional antioxidant, anti-inflammatory, and hepato-protective, activities [20][21][22][23][24][25][26] . In this research, the C-PE is purified and characterized from a marine cyanobacterial strain Nostoc sp.…”

Marine cyanobacteria present a significant potential source of new bioactive compounds with vast structural diversity and relevant antimicrobial and antioxidant activities. Phycobiliproteins (PBPs) like phycocyanin (PC), phycoerythrin (PE), and water-soluble cyanobacterial photosynthetic pigments, have exhibited strong pharmacological activities and been used as natural food additives. In this study, phycoerythrin (PE) isolated from a marine strain of cyanobacterium Nostoc sp. Ft salt, was applied for the first time as a natural antimicrobial as well as an antioxidant to increase the shelf life of fresh rainbow trout i.e., (Oncorhynchus mykiss) fillets. Fresh trout fillets were marinated in analytical grade PE (3.9 μg/mL) prepared in citric acid (4 mg/mL), and stored at 4 °C and 8 °C for 21 days. Microbiological analysis, antioxidant activity and organoleptic evaluation of both control and treated fish fillets were then statistically compared. The results demonstrated noticeable (P < 0.05) differences in the microbial counts, antioxidant activity, and organoleptic characteristic values between PE-treated and non-treated groups. In addition, we observed that treating fresh fish fillets with a PE solution leads to a significant increase in shelf life by at least 14 days. Consequently, PE could be an alternative to synthetic chemical additives since it does not contain the potentially dangerous residues of the synthetic chemical additives and is thus healthier to the consumers.

The ocean is a valuable natural resource that contains numerous biologically active compounds with various bioactivities. The marine environment comprises unexplored sources that can be utilized to isolate novel compounds with bioactive properties. Marine cyanobacteria are an excellent source of bioactive compounds that have applications in human health, biofuel, cosmetics, and bioremediation. These cyanobacteria exhibit bioactive properties such as anti-inflammatory, anti-cancer, anti-bacterial, anti-parasitic, anti-diabetic, anti-viral, antioxidant, anti-aging, and anti-obesity effects, making them promising candidates for drug development. In recent decades, researchers have focused on isolating novel bioactive compounds from different marine cyanobacteria species for the development of therapeutics for various diseases that affect human health. This review provides an update on recent studies that explore the bioactive properties of marine cyanobacteria, with a particular focus on their potential use in human health applications.

“…Antimicrobial effects of the cyanobacteria extracts against pathogens were detected for the presence of various secondary metabolites 23 . The antimicrobial activity of the sub-aerial Cyanobacteria extract could be due to the presence of different chemicals that may include fatty acids, alkaloids, flavonoids, phenolic compounds, quinones, and steroids.…”

Background and Objectives: Cyanobacteria are rich in various bioactive compounds. This study aims to screen the antimicrobial activity of subaerial Cyanobacteria isolated from sub-aerial habitats (Old monuments and building facades). Materials and Methods: Crude aqueous and organic extracts were screened for phytochemical constituents and tested for their antimicrobial efficacy against human pathogens. The crude extract that showed better antimicrobial activities were further fractionated by column chromatography and purified by TLC. The active bands were scraped out separately and concentrated in vacuo to isolate pure compounds. Each purified compounds dissolved in respective solvents, assayed for antimicrobial activities were further characterised through FTIR and LC-MS. Results: The results indicated the presence of many secondary metabolites. Of the isolated purified compounds, the compounds from three species, viz. Scytonema hyalinum, Tolypothrix rechingeri, and Fischerella species exhibited antimicrobial activities, whereas others showed antibacterial activity. The FTIR spectra revealed the peaks of carboxylic acid, alkaloids, and phenolic compounds. The chemical compounds were identified as 1,3-dihydroxycyclohexane [Lyngbya kuetzingiana], 4-(4-hydroxyphenyl) butanoic acid [Nostoc linckia], octahydro-1H-indole-2-carboxylic acid [Scytonema sp., S. pseudoguyanensis, S. pseudohofmani], ergost-5-en-3-ol [Scytonema hyalinum],7,11-dihydroxysolasodine [Scytonema ocellatum], 2, 4-Bis (2-methyl-2-propanyl)phenol-phosphorous acid [Tolypothrix rechingeri] and Pentaphenyl ferrocene carboxamide [Fischerella sp.] respectively. Conclusion:Though it is firsthand information regarding the isolation of sub-aerial Cyanobacteria, with a production of different bioactive chemical compounds, further investigation is required for use in pharmaceutical industries against costly harmful antibiotics and chemotherapeutics. INTRODUCTION:The development of multidrug resistance (MDR) among pathogens is a global concern today. This necessitates the demand for the discovery of the new source of chemical compounds as alternative antibiotics.
